2020 Madagascar School in Hefei

 

Introduction

Madagascar provides a complete environment for organizing one's research, from new software development to running computational experiments to publishing the experimental results in papers and reports, archiving them for future usage, and sharing them with colleagues and sponsors. Madagascar school has been organized many times around the word. It provides a platform for Madagascar users to learn and communicate with the developers. This Madagascar school will introduce the fundamental usages for the beginners with less knowledge of Madagascar and focus on the topic about Open-Source Geophysics in China. This Madagascar school is convened by 1st Asia-Pacific Geophysics Student Conference (APGSC) and hosted by Prof. Yang Liu from Jilin University.

Agenda

Sunday, September 6, 2020
8:30-8:40 Welcome
8:40-10:10 Introduction to Madagascar Software Project (Yang Liu)

The Madagascar project has been in public existence for fourteen years. Madagascar provides a complete environment for organizing one's research, from new software development to running computational experiments to publishing the experimental results in papers and reports, archiving them for future usage, and sharing them with colleagues and sponsors. The introductory presentation will describe the origin and history of the project, the Madagascar components and design principles, and plans for future development. In this module, you will learn how to take the full advantage of the Madagascar environment to enhance research productivity and research collaboration.

Slides (5.9M)

Example

10:10-10:20 break
10:20-11:50 Geophysical data processing with Madagascar (Yang Liu)

Filed data processing is always a tough problem, which is an important test of integrality degree for Open-source geophysics software and the final target for scientific research. We will use a 2D field seismic dataset to illustrate how Madagascar can set up a common seismic data processing workflow. Meanwhile, we also try to setup the initial processing workflows for other geophysical data, e.g., gravity field data and controlled source electromagnetic (CSEM) synthetic data.

11:50-13:30 Lunch
13:30-15:00 Writing a reproducible paper using Madagascar and SEGTeX (Yang Liu)

From the viewpoint of science, all technical papers should be "reproducible" in the sense that someone of reasonable skill ought to be able to read the paper and then reproduce the results (from Joe Dellinger). SEGTeX is a LaTeX package for geophysical publications, which is a important component in Madagascar Project. SEGTeX consists of class files for Geophysics papers, SEG expanded abstracts, etc, and cumulative bibliography of geophysical publications. In this module, you will learn how to use the Madagascar and SEGTeX to write a reproducible paper.

15:00-15:30 Contributing to Madagascar (Yang Liu)

As a user of Madagascar, you have the right to run the code for any purpose, to make modifications and additions, and to share your modifications with other people under the standard GPL open-source license. Madagascar is an open community, which makes it easy to share your contributions and to collaborate with other users and developers around the world.

Slides (2.1M)

15:30-15:40 break
15:40-16:40 Practice (Students and Yang Liu)

Learn the functions of Madagascar software platform, and do some exercises about the construction of data processing workflow and the writing of reproducible papers.
